Radiation with the Minimum Wavelength as Well as the K

Multiple Choice

Radiation with the minimum wavelength as well as the K x-ray lines are detected for a certain target.The energy of the incident electrons is then doubled, with the result that:

A) the minimum wavelength increases and the wavelengths of the K lines remain the same
B) the minimum wavelength decreases and the wavelengths of the K lines remain the same
C) the minimum wavelength and the wavelengths of the K lines all increase
D) the minimum wavelength and the wavelengths of the K lines all decrease
E) the minimum wavelength increases and the wavelengths of the K lines all decrease
